Compiling gcc also requires the mpfr package to be installed. This I did with
[Homebrew](http://mxcl.github.com/homebrew/).
brew install mpfr

$ brew install mpfr
I downloaded all the sources I needed from [gnu.org](http://gnu.org).

In order not to mess up the source, binutils and gcc were built out of tree.
mkdir build-binutils
cd build-binutils
export PREFIX=/usr/local/cross
export TARGET=i386-elf
../binutils-2.22/configure --target=$TARGET --prefix=$PREFIX --disable-nls
make all
make install

$ ../binutils-2.22/configure --target=$TARGET --prefix=$PREFIX --disable-nls
$ make all
$ make install
And the same for gcc, using the new binutils
cd ..
mkdir build-gcc
cd build-gcc
export PATH=$PATH:$PREFIX/bin
../gcc-4.6.3/configure --target=$TARGET --prefix=$PREFIX --disable-nls --enable-languages=c --without-headers

$ make all-gcc
$ make install-gcc
It's really important to run _make all-gcc_ and _make install-gcc_ and __not__
_make all_ and _make install_ here. It probably works anyway - if you ever
